dalmatian: A Package for Fitting Double Hierarchical Linear Models in R via JAGS and nimble
(Peer reviewed; Journal article, 2021)Traditional regression models, including generalized linear mixed models, focus on understanding the deterministic factors that affect the mean of a response variable. Many biological studies seek to understand non-deterministic ... -
Data for characterization of the optical properties of Atlantic salmon (Salmo salar) blood
(Peer reviewed; Journal article, 2023)Photoplethysmography is a recent addition to physio-logging in Atlantic salmon which can be used for pulse oximetry provided that the properties for light propagation in salmon tissues are known. In this work, optical ... -
A data-derived reference mixture representative of European wastewater treatment plant effluents to complement mixture assessment
(Journal article; Peer reviewed, 2023)Aquatic environments are polluted with a multitude of organic micropollutants, which challenges risk assessment due the complexity and diversity of pollutant mixtures. The recognition that certain source-specific background ... -
A dead giveaway: Foraging vultures and other avian scavengers respond to auditory cues
(Peer reviewed; Journal article, 2020)Carrion represents an unpredictable and widely distributed primary food source for vultures and other avian scavengers. Avian scavengers in African savanna ecosystems are reported to rely exclusively on visual stimuli to ... -
Dead wood profile of a semi-natural boreal forest – implications for sampling
(Journal article; Peer reviewed, 2019)Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead ... -
Dealing with different conceptions of pollution in the Gene Regulation Knowledge Commons
(Peer reviewed; Journal article, 2022)Current research of gene regulatory mechanisms is increasingly dependent on the availability of high-quality information from manually curated databases. Biocurators undertake the task of extracting knowledge claims from ... -
Death signals during plant cell death. Macroscopic study of cell death induced by low pH and eATP.
(Master thesis, 2023)For tiden er forskning på celledød et utviklende og svært interessant tema. Celledød som dødsprosessen i mikroskala er en viktig kontrollmekanisme i alle levende organismer. Spesielt programmert cellulært "selvmord", som ... -
Deciphering biodiversity: On the taxonomy of Northern European Darwin wasps (Hymenoptera: Ichneumonidae)
(Doctoral theses at NTNU;2022:12, Doctoral thesis, 2022)Summary of thesis: Ichneumonid or Darwin wasps is one of, possibly the largest hymenopteran family on earth and constitute a large part of what we commonly refer to as biodiversity. Despite their often large and colorful ... -
Decline of a grey seal (Halichoerus grypus) population in Norway: can per- and polyfluoroalkyl substances be blamed ?
(Master thesis, 2023)Bestanden av gråsel (Halichoerus grypus) i Froan Archipelago har gått drastisk ned siden 2001, og det blir en presserende utfordring å forstå de underliggende årsakene til denne nedgangen. Spesiell oppmerksomhet har blitt ... -
Decomposing demographic contributions to the effective population size with moose as a case study
(Peer reviewed; Journal article, 2020)Levels of random genetic drift are influenced by demographic factors, such as mating system, sex ratio and age structure. The effective population size (N e) is a useful measure for quantifying genetic drift. Evaluating ... -
Decomposing demographic contributions to the effective population size with moose as a case study
(Journal article; Peer reviewed, 2020)Levels of random genetic drift are influenced by demographic factors, such as mating system, sex ratio and age structure. The effective population size (Ne) is a useful measure for quantifying genetic drift. Evaluating ... -
Deficiency in egg rejection in a host species as a response to the absence of brood parasitism
(Journal article, 2015)Different populations of a host species subject to variable patterns of selection due to cuckoo parasitism provide an optimal situation for studying natural selection and coevolution in action. We compared egg appearance ... -
Deficiency syndromes in top predators associated with large-scale changes in the Baltic Sea ecosystem
(Peer reviewed; Journal article, 2020)Vitamin B1 (thiamin) deficiency is an issue periodically affecting a wide range of taxa worldwide. In aquatic pelagic systems, thiamin is mainly produced by bacteria and phytoplankton and is transferred to fish and birds ... -
Degumming of Ballan wrasse (Labrus bergylta) eggs
(Master thesis, 2022)Etterspørselen etter berggylt (Labrus bergylta) har økt gjennom årene på grunn av dens effektivitet som rensefisk for å fjerne lakselus (Lepeophtheirus salmonis) fra oppdrettslaks (Salmo salar) i merder. En av utfordringene ... -
Dehydrin, alcohol dehydrogenase, and central metabolite levels are associated with cold tolerance in diploid strawberry (Fragaria spp.)
(Journal article; Peer reviewed, 2013)The use of artificial freezing tests, identification of biomarkers linked to or directly involved in the low-temperature tolerance processes, could prove useful in applied strawberry breeding. This study was conducted to ... -
Demographic and genetic consequences of dispersal in house sparrows
(Doctoral theses at NTNU;2019:24, Doctoral thesis, 2019)The importance of dispersal in population dynamics is widely acknowledged. Key to understand population consequences of dispersal is by quantifying the demographic and genetic contribution from dispersers. The influence ... -
Demographic and genetic description of Greenland´s only indigenous Atlantic salmon (Salmo salar) population
(Journal article; Peer reviewed, 2018)In Greenland, Atlantic salmon are known to reproduce in only one river, the Kapisillit River. Little is known about the population characteristics or the relationship to other salmon populations across the species range, ... -
The Demographic buffering hypothesis: Evidence and challenges
(Peer reviewed; Journal article, 2020)In (st)age-structured populations, the long-run population growth rate is negatively affected by temporal variation in vital rates. In most cases, natural selection should minimize temporal variation in the vital rates to ... -
Demographic buffering of life histories? Implications of the choice of measurement scale
(Journal article; Peer reviewed, 2016)Life-history theory predicts that the vital rates that influence population growth the most should be buffered against environmental fluctuations due to selection for reduced variation. However, it remains unclear whether ... -
Demographic buffering of vital rates in age-structured populations
(Doctoral theses at NTNU;2021:353, Doctoral thesis, 2021)Stochastic demography is essential to accurately predict how populations persist in variable environments. In age- or stage-structured populations, the long-run growth rate is negatively affected by temporal variance in ...
